blk_queue_enter() accepts BLK_MQ_REQ_PM requests independent of the runtime power management state. Now that SCSI domain validation no longer depends on this behavior, modify the behavior of blk_queue_enter() as follows: - Do not accept any requests while suspended. - Only process power management requests while suspending or resuming. Submitting BLK_MQ_REQ_PM requests to a device that is runtime suspended causes runtime-suspended devices not to resume as they should. The request which should cause a runtime resume instead gets issued directly, without resuming the device first. Of course the device can't handle it properly, the I/O fails, and the device remains suspended. The problem is fixed by checking that the queue's runtime-PM status isn't RPM_SUSPENDED before allowing a request to be issued, and queuing a runtime-resume request if it is. In particular, the inline blk_pm_request_resume() routine is renamed blk_pm_resume_queue() and the code is unified by merging the surrounding checks into the routine. If the queue isn't set up for runtime PM, or there currently is no restriction on allowed requests, the request is allowed. Likewise if the BLK_MQ_REQ_PM flag is set and the status isn't RPM_SUSPENDED. Otherwise a runtime resume is queued and the request is blocked until conditions are more suitable.

Instead of submitting all SCSI commands submitted with scsi_execute() to a SCSI device if rpm_status != RPM_ACTIVE, only submit RQF_PM (power management requests) if rpm_status != RPM_ACTIVE. This patch makes the SCSI core handle the runtime power management status (rpm_status) as it should be handled.

RQF_PREEMPT is used for two different purposes in the legacy IDE code: 1. To mark power management requests. 2. To mark requests that should preempt another request. An (old) explanation of that feature is as follows: "The IDE driver in the Linux kernel normally uses a series of busywait delays during its initialization. When the driver executes these busywaits, the kernel does nothing for the duration of the wait. The time spent in these waits could be used for other initialization activities, if they could be run concurrently with these waits. More specifically, busywait-style delays such as udelay() in module init functions inhibit kernel preemption because the Big Kernel Lock is held, while yielding APIs such as schedule_timeout() allow preemption. This is true because the kernel handles the BKL specially and releases and reacquires it across reschedules allowed by the current thread. This IDE-preempt specification requires that the driver eliminate these busywaits and replace them with a mechanism that allows other work to proceed while the IDE driver is initializing." Since I haven't found an implementation of (2), do not set the PREEMPT flag for sense requests. This patch causes sense requests to be postponed while a drive is suspended instead of being submitted to ide_queue_rq(). If it would ever be necessary to restore the IDE PREEMPT functionality, that can be done by introducing a new flag in struct ide_request.

With the current implementation the following race can happen: * blk_pre_runtime_suspend() calls blk_freeze_queue_start() and blk_mq_unfreeze_queue(). * blk_queue_enter() calls blk_queue_pm_only() and that function returns true. * blk_queue_enter() calls blk_pm_request_resume() and that function does not call pm_request_resume() because the queue runtime status is RPM_ACTIVE. * blk_pre_runtime_suspend() changes the queue status into RPM_SUSPENDING. Fix this race by changing the queue runtime status into RPM_SUSPENDING before switching q_usage_counter to atomic mode.

The expectation for suspend-to-disk is that devices will be powered-off, so the UFS device should be put in PowerDown mode. If spm_lvl is not 5, then that will not happen.

Currently, ufshcd-pci is the only UFS driver with support for suspend-to-disk PM callbacks (i.e. freeze/thaw/restore/poweroff). These callbacks are set by the macro SET_SYSTEM_SLEEP_PM_OPS to the same functions as system suspend/resume. That will work with spm_lvl 5 because spm_lvl 5 will result in a full restore for the ->restore() callback. In the absence of a full restore, the host controller registers will have values set up by the restore kernel (the kernel that boots and loads the restore image) which are not necessarily the same. However it turns out, the only registers that sometimes need restore are the base address registers. This has gone un-noticed because, depending on IOMMU settings, the kernel can end up allocating the same addresses every time. For Intel controllers, an spm_lvl other than 5 can be used, so to support S4 (suspend-to-disk) with spm_lvl other than 5, restore the base address registers.

The user can set trigger values in order to collect the IOC's host trace buffer automatically upon detecting certain conditions. However, the trigger values that the user sets are not persistent across system reboot or reload of the driver. In order to make the user trigger settings persistent, these trigger values need to be saved in the IOC's NVRAM pages: - Driver Persistent Trigger Page 0: This page is used to store list of trigger types that are enabled - Driver Persistent Trigger Page 1: This page stores the list of Master triggers that are enabled - Driver Persistent Trigger Page 2: This page stores the list of MPI Event Triggers that are enabled - Driver Persistent Trigger Page 3: This page stores the list of SCSI Sense Triggers that are enabled - Driver Persistent Trigger Page 4: This page stores the list of IOCStatus-LogInfo Triggers that are enabled. Whenever user configures triggers, the driver persists the values in the corresponding trigger pages. When the driver is subsequently reloaded, the driver reads the values from the trigger pages and configures the triggers accordingly. During firmware upload operation, if the newer firmware supports the trigger page feature, then driver persists the configured diag trigger values to NVRAM.

The controller time currently gets updated with host time during driver load or when a controller reset is issued. I.e. when host issues the IOCInit request message to the HBA firmware. This IOCInit message has a field named 'TimeStamp' with which the host updates the controller time. Sometimes controller time drifts with respect to the host and it is difficult to correlate host logs with controller logs. Issuing a controller reset to sync the time would impact in-flight I/O and is not a viable option. Instead the driver now sends an IO_UNIT_CONTROL Request to sync the time periodically. This is done from the watchdog thread which gets invoked every second. The time synchronization interval is specified in the 'TimeSyncInterval' field in Manufacturing Page11 by the controller: TimeSyncInterval - 8 bits bits 0-6: Time stamp Synchronization interval value bit 7: Time stamp Synchronization interval unit, (if this bit is one then Timestamp Synchronization interval value is specified in terms of hours else Timestamp Synchronization interval value is specified in terms of minutes). The driver keeps track of the timer using IOC's timestamp_update_count field. This field value gets incremented whenever the watchdog thread gets invoked. And whenever this field value is greater than or equal to the Time Stamp Synchronization interval value, the driver sends the IO_UNIT_CONTROL Request message to controller to update the time and then it resets the timestamp_update_count field to zero.
